About this 0.9ct natural marquise diamond

This 0.9ct natural marquise sits in the just-under-one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2554644256. Listed at 13 retailers as of October 31, 2026, with prices from HK$19,362 to HK$36,122, a HK$16,759 spread on the same certified stone. Helzberg Diamonds lists it at HK$36,122. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
